rIhis invention relates to a mechanical movement applicable to many diiierent uses.

I have herein disclosed one preferred form of this mechanical movement as embodied in a corrective device adapted to be used in administering corrective treatments to the muscles, bones and tissues of the feet, ankles, legs, hips and lower abdominal portions of the body.

A primary object of this invention is to provide a mechanical movement which, when embodied in a foot corrective device, will manipulate and move the feet and ankles in such a manner as to correct the position or the bones in the feet, relieve pressure on the nerves and blood vessels, overcome unnatural Shapes which have been produced by the wearing of tight and improperly constructed shoes and generally restore the feet and ankles and legs to a stronger and more healthy and more normal condition.

Another object is to provide a foot corrective device which will improve the `physical condition and posture of the entire body by strengthening and normalizing the feet and ankles and legs.

The feet are the foundation on which the human body is carried and the physical condition of the feet has an eiect on the condition of other parts of the body. Under modern living conditions, people are liable to Wear incorrectly shaped, high heeled, tight, ill iitting, shoes. Many people Walk very little and only on smooth surfaces, as iioors and level sidewalks. Walking on these smooth surfaces does not subject all of the muscles and bones of the feet and ankles to the use and movement required to keep them in a strong and healthy condition. The result is that the foot muscles deteriorate and allow the arches of the feet to flatten, displacing the tarsal and metatarsal bones and subjecting the blood vessels and nerves in the foot to unnatural pressures. This tends to obstruct the circulation in the feet, ankles and legs and restricts and irritates the nerves which lead to the feet and ankles. As the nerves which lead to the feet and those which lead to the lower abdominal organs all emanate from the spine at the location of the small of the back, an irritation of the nerves oi the feet is very liable to cause trouble with the organs of the addomen.

This mechanical movement when embodied in a foot corrective device provides an easy and enicient means for obviating, overcoming and correcting the troubles above pointed out by making it relatively easy for a user of the device to subject the feet, ankles and legs at frequent intervals, to corrective movements which will strengthen the muscles, stimulate the circulation, restore the bones to normal position and relieve abnormal pressures on the nerves and blood vessels. These movements are, to a certain extent, communicated to the legs and lower portions of the body and are particularly benecial in reducing swollen ankles and varicose veins in the legs and in bringing about a more healthy condition of the lower abdominal organs.

A further object of this invention is to provide a mechanical movement oi this nature which is well adapted to be employed in the construction oi a foot corrective device having two iootplates, Said mechanical movement making it possible to simultaneously impart a wabbling movement and an oscillating movement to the two footplates and providing for reversal of the direction of Wabbling movement of the footplates and for adjustment of the amplitude of said wabbling movement, and providing for independent adjustment of the amplitude of the oscillating movement of the two foot plates and for angular adjustment of the position of the arc of said oscillating movement and for total suppression of said oscillating movement o said footplates and said mechanical movement further providing for independent adjustment of the two iootplates both sidewise and forwardly and rearwardly as respects the upright supports of the footplates.

Further objects of the invention are to provide a mechanical movement of this nature which is adjustablei'as to speed and amplitude of movement while the machine is in operation and which is further adjustable as to position so that it may be readily made to conform to the requirements of different individuals when said mechanical movement is embodied in a foot corrective device.

Further objects of the invention are to provide a mechanical movement in which the parts thereof are of simple strong and durable construction and in which the movement is well adapted for the purpose described.

The drawings show my mechanical movement as embodied in a foot corrective device, comprising a rectangular housing having a bottom I, front wall 2, rear wall 3, two end walls 4 and a top portion or cov-er 5. The operating mechanism is mounted within this rectangular housing. This mechanism comprises two upright posts or shafts 6 and I positioned in spaced apart relation within the housing and adapted to support foot plate means as hereinafter described.

The shaft mounting and driving means and the footplate supporting, moving and adjusting means is in duplicate for each of shafts S and l. This description refers to said means as applied to shaft 6 but will be understood to apply equally well to the means connected with shaft I. The lower end portion of each upright post 6 and rI is supported by a ball bearing 8 mounted in the bottom portion I of the housing, see Figs, 3 and 4. Each post E and l is further supported by a ball bearing 9 mounted in the top plate 5 of the housing.

The means for rotatably driving the two upright shafts 6 and 'I comprises a reversible electric motor Il), Fig. 2, having a variable speed pulley comprising two discs II and I2 with opposed conical faces positioned in opposed relation, with one disc II preferably secured to the shaft I3 of the motor and the other disc I2 movable toward and away from the disc I I and urged toward the disc II by a compression spring III. The variable speed pulley illustrated in the drawings is commonly known as a Reeves variable speed pulley and is readily obtainable on the market. An endless belt I 5 connects the variable speed pulley II-EE with a pulley I5 on a shaft Il. The shaft I'I is rotatably mounted preferably in ball bearing pillow blocks i 8 which are secured to the bottom portion I of the housing. A ywheel i9 is preferably provided on the shaft I'I to insure a steady and even rotary movement of said shaft in operation, Two worms 2() on the shaft il operatively engage with two worm Wheels 2l on the upright shafts and I providing reduction speed gear means for transmitting rotation from the shaft II to the shafts 5 and "I, The worms 2G and worm wheels ZI are disposed in housings 22, To provide for varying the speed ratio between the variable speed pulley on the motor shaft I 3 and the pulley I5 on the shaft I'l, the motor it is movably mounted on two track members 23 which are secured to the bottom portion i of the housing and extend transversely thereof so that the motor` can be moved on these track members toward and away from the shaft I'I. The means for moving the motor Il] on the track members 23 comprises a push and pull rod 24 having one end portion i'iXedly secured to the motor and the other end portion Xedly secured to the lower end portion of an upright yoke 25. Another push and pull rod 26 is xedly secured to the upper end portion of the upright yoke 25. The forward end portion of the push and pull rod 26 is threaded into a sleeve 2'! which extends outwardly through the front wall 2 of the housing and has crank means 28 secured thereto by which the said sleeve may be rotated. The front wall 2 of the housing forms a bearing for the sleeve 2l' and said sleeve and the crank member 28 are provided with suitable thrust means to engage the housing and prevent longitudinal movement of the sleeve. Rotation of the sleeve will mov-e the push and pull rods 24 and 26 longitudinally and will move the motor Il) toward and away from the shaft I'I. The upright yoke 25 serves as a means for rigidly connecting together the two push and pull rods 2li and 2S and as a means for elevating the push and pull rod 26 high enough so that the crank means 28 may be conveniently operated. When the motor I is moved on the track members 23 the variable speed pulley will be moved simultaneously therewith and the effective diameter of the variable speed pulley as respects the endless belt I5 will be varied, This varies the driving ratio between the variable speed pulley I I I2 and the pulley I5 on the shaft I'I. For instance, if the variable speed pulley II I2 is moved toward the pulley I6 it will tend to slacken the belt I5. As the belt I5 slackens the spring Ill will move the disc I2 toward the disc II thus crowding the belt I5 outwardly between the cone shaped discs II and I2 and simultaneously taking up the slack in the belt. This increases the effective working diameter of the cone shaped discs H I2 as respects the belt I5 and steps up the gear ratio between the variable speed pulley II-IZ and the pulley I 6. Conversely, movement of the variable speed pulley I I EZ in a direction away from the pulley I6 will draw the belt E5 between the cone shaped disc members II and I2 toward the aXis of said members II and I2, and move the cone shaped disc member I2 away from the cone shaped disc member Il. This lowers the gear ratio of the pulley li-l'Z relative to the pulley I6. The Variable speed drive hereinbefore described is substantially noiseless in operation thus making it very desirable for use on a foot corrective device of this class.

The upper end portion of each shaft Ei and l is seated within a socket in a forked bracket member 3i! and is fixedly secured to said bracket mem`1 ber 3b as by a set screw 3i so that the bracket member and shaft will rotate together. A cup shaped member 32 is pivotally mounted in the bracket member t@ by two relatively aligned pivot studs t3. The common axis of the pivot studs 33 is at right angles to the axis of rotation of the upright shaft on which the bracket member iii! is mounted, An arcuate worm segment 3d is rigidly connected with the lower portion of each cup shaped member The worm segment 34 is arcuate and has a center which coincides with the axis which is common to the two pivot studs 33. An adjusting screw' i5 is rotatably mounted in the bracket 3U and has threads which mesh with the threads of the worm segment 3d. The angular position of the cup shaped member 32 relative to the bracket tu may be varied by turning the adjusting screw Sib. This provides for varying the angular position of the cup shaped member relative to the axis of rotation of the bracket 3f! and the shaft on which it is mounted.

The cup shaped member 32 has a receptacle in the upper portion thereof for the reception of a ball bearing Sli. The ball bearing d receives and rotatably supports a downwardly extending stub shaft Iii of a footplate supporting member 33. An adjustable block tti has a dove tail connection il with the foot plate supporting member 38. A screw l2 is provided for adjusting the block itil into any desired position relative to the member 38. Another block i3 has a dove tail connection fill with the block it and is adjustable in directions at right angles to the direction of adjustment of the block tu. A screw 45 is provided for adjusting the block d3. A dish shaped foot plate dit is secured to the block i3 and a lining dll of padding material, as soft rubber, is preferably provided in the footplate do,

The footplate moimting means just described provides upright rotatable means comprising the shaft t and bracket member td, inciined crank means on the upper end portion of the rotatable means capable of having the angle thereof varied or adjusted by the sore-w 35 and worm segment 3d, said inclined crank means comprising the pivotally mounted cup shaped member t2, ball bearing (it, stub shaft 3l and footplate supporting member 3B; vand a iootplate mounted on the inclined crank means so that it can be adjusted in two directions at right angles to each other relative to the inclined crank means. The incline of the axis of the ball bearing 3s relative to the shaft will produce a wabbling motion to the footpl'ate and the amount of this wabbling motion may be increased by increasing the angle of incline of the airis of said bearing relative to the shaft and may be decreased by decreasing the angle of incline of the axis of the bearing Citi relative to the shaft t. When the axis of the stub shaft ii'i coincides with and is aligned with the axis of the shaft t there will be no wabbling motion imparted to the footplate by rotation of shaft ti but when the axis of the stub shaft 3l is inclined relative to the axis of the shaft i, as shown in Fig. 12, then rotation of the shaft will impart a wabbling or swash plate movement to the footplate.

The adjustments of the footplates provided by the screws l2 and i5 serve to move said footplates off center as respects the shaft 6. This provides for more bending of the ankle in one direction.

In addition to the wabbling motion to be im parted to each footplate it is desired to simultaneously impart an oscillating motion in generally horizontal directions to each footplate. This oscillating` motion imparts a toe-in and toeout motion to the foot and in so doing imparts 'a twisting motion to the leg. 'Also it is desirable to be able to vary the amplitude or extent of horizontal oscillation of each foot plate and to entirely suppress or eliminate this horizontal oscillation of either foot piate. t is further desirable to provide means for angularly adjusting the zone of oscillation of each foot plate independently, so that the machine may be adjusted to obtain the best results with persons who toe-in or with persons who toe-out or with persons whose feet are deformed so that the two feet do not point in the same direction. All of the above mentioned movements and adjustments are obtained by the mechanism hereinafter described and which is provided in duplicate in connection with each shaft 6 and l and the foot plate supporting member 3B connected therewith.

The means for oscillating each footplate i6 to impart thereto a toe-in 4and toe-out movement comprises an upright telescopic arm positioned rearwardly from each shaft 5 and i and extending from the interior of the housing upwardly to la point at the rear of the adjacent footplate supporting member 33. Each telescopic arm comprises a tube 5t and a piston member 5i telescopically `disposed within the tube 5t! and extending upwardly therefrom. The upper end portion of each piston member 5l has an enlarged head portion i9 which is connected by two pivot studs 52 with a tubular sleeve 53 which fits slidably and rotatably over a cylindrical shank 5d that is rigid with and extends rearwardly from the adjacent footplate supporting member 38. The common axis of the pivot studs 52 is at right angles to the axis of the shank Eli and intersects said axis of said shank 5d. This. provides freedom of movement between the shank 5d and piston member iii as it allows relative oscillation on the pivot studs 52, oscillation of the tubular sleeve E3 on the shank 5d and longitudinal sliding movement of the shank iid within the tubular sleeve tit. lThe head portion i9 of each piston 5l has an opening 55 therein oi large enough size to provide operating clearance for the tubular sleeve 53 for all positions required in the operation of the device. The pivot studs 52 are rigid with the tubular sleeve iid. For convenience in` assembly the head portion il may be slotted for the reception of the pivot studs 53 and removable retainer members 56 may be secured to the head portion di) by screws 5l' to complete the assembly.

The tube 5b is supported within a pivotally mounted bracket 5d and said tube 5i] extends upwardly through an arcuate slot 6i! in the housing cover 5 and a corresponding arcuate slot Si in a cap member b2 which is secured to the housing cover 5. Preferably a bottom supporting ring b3 is disposed between the cap member 62 and the top ti of the housing and a top slide ring Gi is positioned on top of the ring b3. The top slide ring iid is prefer-ably movable with the tube 5G and the bottom supporting ring is preferably stationary and has an arcuate slot registering with slots 60 and 6I in the housing top 5 and the cap member S2. yThe tube Sii is preferably secured by a screw 5i to the bracket 58 so that its weight is supported thereby, see Fig. 5.

The bracket 5S has a foot portion S5 which rests upon a collar S5 on the shaft as shown in Fig. 5. The collar 55 is positioned just above the gear housing 29. The bracket 58 also has an upper portion El spaced a substantial distance above the foot portion E5. The shaft 6, Fig. 5, extends through both the upper portion 5l and foot portion 55 so that the bracket 53 is pivotally movable about the shaft 6 of an axis. Obviously, pivotally moving the bracket 53 will move the tube 50 and piston member 5i in an arc corresponding to the slot 6! shown in Fig. 2, and this will oscillate the footplate i6 back and forth about the axis of the stub shaft 3i thus imparting to said footplate a toe-in `and toe-out movement simultaneously with the wabbling movement of said footplate. The wabbling movement of the footplate will necessarily result in imparting a vertical movement to the piston 5i and this vertical movement will be taken care of by sliding movement of the piston 5i within the tube 563. Also the footplate oscillating may be rendered inoperative by means which will presently be described.

The bracket 58 together with the sleeve 5!) and piston 5i is oscillated by an eccentric disc 68 mounted on the upright shaft 5, Figs. 2, 4, 5, 10 and ll. The eccentric disc 68 is positioned within an eccentric yoke 'd that is Slidable on two spaced apart parallel rods or bars li. The rear ends of the bars 'H extend through a swivel block 'i2 which is positioned within a recess 'i3 in the bracket 53 and is pivoted on the tube Sii, see Figs. 2. 5. l and ll. The forward ends of the bars il secured to a cross bar lli. The cross bar M is; pivotaily mounted on a stud 'i5 which extends downwardly from a slide block 1S. The slide block 'ifi is slidably adjustably connected by dove tail means 'il with a track member and lever arm 'i8 which is pivotally connected with the adjacent upright shaft 6 and is angularly movable. This ermits the bars il to be angularly moved and the slide block iii to be moved toward and away from the adjacent upright shaft S. As the slide block is: carries the pivot 'i5 about which the bars '5i swing it will be obvious that movement or" this pivot 'E5 toward and away from the eccentric disc 5S will vary the distance of movement of the tube 5? and thus vary the amplitude of oscillation of the foot plate. Fig. 1i) illustrates the two maximum angular positions of the bars ii when the pivot member 'i5 is withdrawn to a distance from the shaft 6 and 1l illustrates the greater angle which will bewimparted to said bars when the pivot l5 is moved closer to the shaft 6. The track member and lever arm 'iS has an integral handle portion Se which extends outwardly from the front side of the housing through a transverse slot 8 i. The handle portion 35, see Fig. 8, has a longitudinal bore 82 within which is disposed a tubular sleeve The inner end portion of the sleeve 83 has an enlarged portion Sli thereon which limits outward movement of the sleeve 83 within the handle portion Sii. The portion of the sleeve 83 adjacent the enlarged portion Si is of large enough diameter to fit snugly within the bore B2 of the handle portion 85 and the remainder of the length of said sleeve 83 is of smaller external diameter so as to leave an annular space 85 between it and the wall of the bore 32 of the handle 8S. The outer end of the sleeve 83 extends beyond the outer end of the handle portion 8i) and is seated within a receptacle 85 in a knob 8?. A set screw 88 secures the knob 8i to the sleeve 83 so that when the knob 8i is rotatively moved the sleeve 83 will be rotated therewith. A thread 5i! is provided on the exterior of that portion of the sleeve E3 between the inner end of the knob 8l and the larger inner end portion of the sleeve 83. An internally threaded ring member Si is positioned on the sleeve 83 with the internal threads thereof engaging the threads :it of the sleeve 83 and said ring member 9| is movable lengthwise oi' the space 85 in response to rotation of the sleeve 83. The pitch of the thread 93 is less and preferably about one half the pitch of the internal thread of the member 83 so that the ring member 9! will travel substantially one half as fast as a stem 56 when member 83 is rotated. A screw 92, rigid with the ring mem-ber 9i, extends upwardly through a slot SS in the handle member 3i). A pointer 95, Fig. 9, is provided on the screw 92. Graduation marks 5 are provided on the handle 80 for cooperation with the pointer Sli to indicate the degree of lateral sweep or extent of oscillation which will be imparted to the ootplate for all positions into which the pointer 9d may be moved.

The sleeve 83 also has an axial bore which is threaded for the reception of an externally threaded stem 96. The inner end of the stem 96 is rigidly connected with the slide block i6 so that longitudinal movement of said stem Q6 will move the slide block i5 together with the pivot 'I5 and cross bar 'iii toward or away from the upright shaft ii. Rotation of the knob 8i will rotate the sleeve 83 and thereby longitudinally move both the stem 5S and the ring member Si which carries the pointer 955. The longitudinal movement of the stem will adjust the amplitude of oscillation of the foot plate and the longitudinal movement of the ring member ill will position the pointer 95. as respects the graduation marks S5 so as to correctly indicate the amplitude of these oscillations. The graduations Q5 may represent degrees of oscillation or they may indicate any other desired unit. Adjustment of the amplitude of oscillation may be made while the machine is running.

The track member and lever arm i8, pivoted on shaft 6, and the handle 8S, integral with said track member i8, serve as a means for angularly positioning the foot plate 36. To provide eiiicient means to releasabiy lock these parts in any desired angular position I provide a latch member Si secured to a rod 98 which is slidably movable within the stem 9G. The latch member Si projects downward-ly through a slot itt in the rod 98 and is engageable within notches iill in an arcuate segment i632, Figs. 2, 3 and 5, which is made rigid with the iront portion of the housing. The outer end portion of the rod 98 is secured to a push button ii which projects from the end of the knob 3?. A compression spring |05 is interposed between the inner end of the push button 53 and a washer 55 which rests against the end of the tubular sleeve 83. This compression spring ii thus exerts a yielding pressure against the push button 03 tending to hold the latch member Si in engagement with the notched segment |52. By pressing the push button E03 inwardly the latch member 97 will be disengaged from the notches i0! in the arcuate segment |02 and the lever composed of track member 'i8 and handle 8G maybe angularly moved relative to the post t. The mechanism which carries the upright tube member Eiii and piston is connected with the track member 'iii and will be angularly moved therewith with the result that the footplate will be similarly moved into any desired angular position. Preferably the handle Bil is provided with pointer means itil, Fig. 5, which indicates, by its relation to graduations ll'l, Fig. 2, on the frame plate 5, the angular position of the footplate. The feet of some persons normally tend to toe-in, the feet of some normally point straight ahead and the feet of others normally tend to toe-out. On persons who have abnormal feet the two feet may point in diderent directions. Also normal feet can be angularly moved outwardly farther than they can be moved inwardly from their normal position Without placing them under undesirable strain. For these reasons it is desirable to be able to independently adjust the angular positions of the two footplates it to suit the feet of the individual patient. This adjustment can be made before starting the machine or while the machine is operating.

When the levers lilils in the machine shown in the drawings are set so as to position the point ers Hit at Zero on the graduations liil' the foot plates it will point substantially straight ahead providing the eccentric discs tu are in the position shown in Figs. 2, 3 and 5 or at one hundred eighty degrees to this position. Obviously the graduations iol may be differently arranged or the relative angular positions of the footplates it and levers lil-sli may be varied.

For the purpose of securely holding the combined lever arm and track bar lil in any position into which it is adjusted and to prevent vibration and relieve the latch member Sil of strain when oscillatory movement is being imparted to the bars 1| and parts connected there- With, I provide clamping means for this track bar. This clamping means comprises a thumb nut ltiil threaded onto a stud bolt ll which extends through an arcuate slot ft2 in the top plate 5 and is threaded through the track bar TF8 at location |53. Bolt l5! has a head portion |542- jammed tightly against the track bar lil. A recess in the slide block 'It provides clearance for head Ii'ill. When the lever 'iii-Ml is to be angularly moved the nut itil is loosened. After this lever has been properly positioned the nut |50 is tightened so as to securely hold the track member 'it in fixed position, prevent vibration of the support for the pivot l5 and relieve the latch member El of strain.

The eccentric disc foo-tplate oscillatingmeans will oscillate the footplates substantially equal distances in opposite directions from the position occupied by said footplates when said eccentric discs t8 are in the mid position shown in Fig. 2. The maximum angular positions of the footplate oscillating means are shown in Figs. 10 and 11. The fact that the human foot will toe-in further than it will toe-out without undue strain may be taken into account in initially setting the levers 'lil- Su and these levers may be set so that the oscillating means will angularly move the footv outwardly further than it will move said foot inwardly from the normal position of the foot.

Brass washers 'i9 are preferably provided on the shaft ii at locations where relatively rotatable and nonrotatable parts come together, to

minimize Wear and reduce friction at these locations.

In some instances it may be desirable to disconnect the footplate oscillating means and impart onlya wabbling or swash plate motion to the footplates. To accomplish this the eccentric disc 63 is preferably rotatably mounted on the shaft 6 and suitable clutch means is provided for selectively connecting or disconnecting the eccentric disc from the shaft as respects rotary movement of said eccentric disc on said shaft. Preferably this clutch means comprises a collar |08 having a flange lub on its lower end' portion. This collar lull is splined to the shaft 6 by a key or spline |69 so that said collar is free to move longitudinally of the shaft 6 but must rotate with said shaft The collar |03, see Figs. 5 and 7, has a clutch tooth lill positioned to engage Within a recess lli in the eccentric diso 68 when the collar |08 is in an elevated position and to be withdrawn from said recess when the collar lut is in a lowered position. A compression spring llt is provided on the shaft E between the collar les and the base portion 65 of the bracket E3. This spring I2 yieldingly urges the collar |08 into an elevated position in which the clutch tooth Ilo is projected into the recess lil and locks the collar |08 and eccentric disc @il together for synchronous rotation with the shaft 6. A sleeve ||5 is rotatably mounted on the collar 63 and rests on the flange Hi8. A clutch control arm ||3 has a forked end portion lli which extends over the sleeve H5 and engages with pins H5 on said sleeve l l5 in such a manner that it will move the collar Hill downwardly on the shaft when the forked end portion lill is moved downwardly. Rotation of the sleeve liti is prevented by providing flat sides on said sleeve for engagement with the forked end portion lill of the clutch control arm llt, as shown in Fig. '7. The outer end of the clutch control arm lli-l is connected by a pivot lit with a fixed part of the housing. The operating means for the clutch control arm ||3 comprises a clutch handle l |'l positioned at the front of the housing and connected with a pull rod i it which is longitudinally movable in the front Wall 2 of the housing. A bracket H9 serves as a further means of support for the pull rod liil. The inner end portion of the pull rod H8 is rotatively connected with a forked member |26. The forked member lili is connected by slot and bolt means l2l with a lever arm |22 which is fulcrumed on a shaft lf3. The shaft |23 is supported in upright brackets |24. The clutch control arm M3 is connected by a pivot |25 and link means lil@ and a pivot |21 with the lever arm |22. The lever arm |22 is also provided with a locking pawl |128 adapted to enter and lock Within notches 23 in the foot portion 65 of the swinging bracket 53 to lock said swinging bracket against angular movement when said lever arm |22 is in the position shown in Fig. 5. The pull rod lill is provided with a longitudinal spline itil, Figs. 5 and 6, which is longitudinally movable through a groove i3! in the bracket H9 when it is in alignment with said groove itl. The bracket il@ also has a shallow recess in its front side, preferably at an angle of about ninety degrees from the groove |3|, in which the end portion of the spline |39 will rest when the several parts are in the position shown in Figs. 5 and 6. Preferably two stop lugs or pins |33 and ltd are provided adjacent the recess 32 and groove itl respectively so that they will be engaged by the spline l and rotary movement of the pull rod ||8 thereby limited. When the clutch handle [H and pull rod ||8 are in the position shown in Fig. 3 the clutch tooth |||l will be positioned in the recess of the eccentric disc 68 and the locking pawl |28 will be clear of the notch |23 and the clutch will be in engaged position. To disengage the clutch and lock the bracket 58 against swinging movement the operator grasps the handle longitudinally moves the pull rod H8 outwardly until the spline |30 is clear of the groove |3I, then turns the handle il 'l and rod ||8 counterclockwise substantially ninety degrees until the spline |30 engages the stop pin |33, then releases the handle and allows the end portion of the spline |30 to enter the recess |32, where said spline will remain, due to the action of the spring ||2, until it is manually released. Outward movement of the pull rod H3 will angularly move the lever arm |22 from the position shown in Fig. 3 to the position shown in Fig. 5. This will move the locking pawl |28 into the notch |29 so as to lock the bracket 58 against angular movement and at the same time it will move the forked end of the clutch control arm ||3 downwardly thus moving the collar parts ||l8 and |08' and ||5 downwardly. This withdraws the clutch tooth IIE! from the recess and disengages the clutch. To reengage the clutch the spline |35 is withdrawn from the recess |32 and the pull rod i8 is turned clockwise until the spline |30 encounters the stop pin |34 and then released. This allows the spring ||2 to move the collar |08 upwardly and engage the clutch tooth within the recess of the eccentric disc. At the same time the pull rod ||8 and handle ll'l are moved inwardly into the position shown in Fig. 3.

To indicate the speed at which the shafts Ei and 'l are being driven I provide speed indicator means comprising a speed indicating member |35 rotatably mounted on a bearing |36 and having a graduated arcuate portion |31 which is visible through :a sight opening |38 in the cover portion of the housing. A sheave |39 is secured to the speed indicating member |35 in concentric relation as respects the bearing |36. A exible connector HiB passes around the sheave |39 and is secured to said sheave. This flexible connector passes over suitable guide sheaves lill and is secured to the yoke Iby which the motor I@ is moved to vary the gear ratio of the vari-able speed pulley 2. A tension spring |l2 is connected with the speed indicating member |35 yieldingly urging said speed indicating member in one direction and maintaining a tension on the flexible `connector |40. When the yoke 25 is moved, so as to move the motor to change the gear ratio of the vari-able speed drivin-g pulley |-|2 the flexible connector M0 will either be slackened so as to allow the s-pring U32 to angularly move the speed indicating member |35 in one direction or a pull will be exerted on said iexible connector Ui@ to angularly move the speed indicating member |35 in the other direction. As the motor l operates at a constant speed and the position of this motor determines the speed ratio of the variable speed pulley |||2 it is possible to graduate the member |35 so that it will indicate substantially the speed of rotation of the shafts 6 and Preferably the machine has four supports M3, Fig. 1, which extend upwardly `from locations adjacent the four corners of the machine. The

upper ends of the two supports U43 at each side of the machine are preferably connected with each other by side bar means IM. A cross bar It extends crosswise between the two front upright supports H33 and is slidably and adjusta-bly connected with said two front upright supports, preferably by T fittings M which iit slidably on said supports M3 and have ypins Ifl'l which extend through transverse holes Hi8 in the two front supports |63. The cross bar |65 forms a convenient, vertically adjustable, hand hold for a person who is standing on the footplates. The side bars |44 prevent a person from falling sidewise olf of the machine and said side bars |44 may be used as supports for sling straps Hi8' which are connected with a belt |619 that is adapted to be placed around the waist of a person standing on the foot-plates. The belt |43 will only be used in instances where the person using the machine needs a support in addition to the cross bar M5.

In some cases it may be desirable for a person to use the machine while sitting down. In these cases a seat, as a stool or chair, not shown, is placed directly behind the machine at the correct elevation and the person using the machine sits on this seat and places the feet on the footplates. When the person thus uses the machine while seated it is preferable to extend an adjustable sling member over each knee. These sling members |55 may be partially or entirely of elastic material to provide a resilient pressure and said sling members |55 are preferably secured to rings IE5 on the to-p .plate 5 of the housin-g. A fragment only of one of these slings is shown. By the use of these sling members any desired pressure may be exerted on the knees to hold the feet down on the footplates with as much force as desired.

The various `adjustments provided in connection with the mechanical movement embodied in this device render said mechanical movement well adapted for use in connection with the foot corrective device herein described, or for numerous other uses not herein specifically set forth.

If the stub shaft El' is adjusted into axial alignment with the shaft 5 and the clutch devices disengaged as respects the eccentric disc 68 then operation of the motor l@ in either direction will rotate the shaft 5 without imparting any movement to the footplate. If the clutch means HBS-Ill is engaged while the stub shaft 3l is in axial alignment with the shaft 6 and the machine is then operated the footplate will be oscillated in a horizontal plane. The amplitude of this oscillation may be varied by varying the distance of the pivot 'i5 from the shaft 6, as illustrated in Figs. 10 and 11. Also the angular position of the footplate may be varied by loosening the thumb nut |55, releasing the. catch member 91 and angularly moving the lever B-J8. If the screw 35 is adjusted so as to position the axis of the stub shaft 3l at an angle to the axis of the shaft 6, then, when the shaft 6 is rotated, a wabbling or swash plate movement will be imparted to the footplate. The amplitude of this wabbling movement will vary in .proportion to the angle of the axis of the stub shaft 3l relative to the shaft 6. This swash plate movement may be imparted to the footplate either with the clutch mechanism in engaged or disengaged position. When the swash plate movement is imparted to the footplate with the clutch mechanism in engaged position the resultant will be a combined wabbling and oscillatory movement of the footplate and the amplitude of the oscillatory movement may be adjusted while the machine is running. Also the angular position of the zone of oscillation may be adjusted about the axis of the shaft E, either while the machine is operating or while it is inoperative. The speed of operation may be varied at will, and by reversing the motor, the direction of the swash Iplate movement may be reversed. Also the screws 42 and 45 4may be moved to adjust the .position of the footplate either transversely or longitudinally relative to the axis of the shaft 6.

Indicators are provid-ed to accurately indicate all of the various adjustments and settings of the machine. This makes it possible to quickly and easily adjust the machine to obtain any predetermined setting of the same. This feature is of great advantage when this mechanical movement is embodied in a foot corrective device, as it makes possible quick and easy adjustment of the machine to suit the reuuirements of a plurality of patients who are successively using the machine.

The foot plate adjusting screw 35 may have square holes in the ends 'thereof to facilitate adjustment. The pitch of the threads of this screw ttl is such as to maire it self locking. A pointer 33 secured to one of the pins 33, see Figs. 3 and Li indicates the angular position of the footplate dit by reference to graduations'on the forked bracket member 3d.

Preferably each footplate et, Figs. 15 and 17 is provided near the toe portion with a plurality of metatarsal positioners it? of various sizes and shapes and thicknesses. Each positioner i5? has a shank H adapted to fit within a suitable recess in the foot plate. The Shanks 15d are differently positioned on the different members l5] and are preferably rectangular and fit into rectangular holes itil in the footplate. By interchanging and reversing these positioners various adjustments are secured. One positioner 151 is omitted in Fig. 15 to show the hole its. The scale in Fig. 1'?, is larger than in Fig. 15. These metatarsal positioners are located under the metatarsal portion of the foot so as to properly support feet of different `shapes which are being treated. A substantially wedge shaped interchangeable arch support it@ Figs. ,1.5 and lo' having dowel pins 15iwhich t within suitable holes in the footplate [it is also provided for use in the footplate 4t to support the arch of the foot when needed. Also two os calcis positioners comprising screws I 62 threaded through balls i553 in sockets iil in the heel portion of the footplate are provided. The screws it? have flattened knob portions E65 secured to their inner ends by universal joints itt for positioning and supporting the heel portion of the foot. All of the supporting devices just described are separated from direct contact with the feet by proper padding, when in use. For instance, the sponge rubber lining 4.1i may be interposed between the foot and the supporting members itl, itil and iSd.

Figs. 18 to 21 show a modified form of the invention. These figures disclose mechanism for adjusting the angle of a footplate while the machine is running. Also these figures disclose a dual or two part footplate especially designed to impart a corrective movement to the mediotarsal joints of the foot. Also these figures disclose modified indicator means for indicating the amplitude of the wabbling movement which is being imparted to the footplate. The means for adjusting the amplitude of wabbling movement While the machine is operating is useful when this mechanical movement is embodied in mechanisms other than foot corrective devices.

Referring to Figs. 18 to 21, fragments of the bottom l, front wall 3 and top or cover Ei of the housing are designated by the same numerals as in the preceeding gures. The alternative mechanism comprises a bearing cup itil, pivoted by bearing studs itl in the forked upper end portion |62 of a bracket member |63. This pivotal mounting provides for tilting movement of the bearing cup Kill by an off-center connection to said bearing cup, as hereinafter set forth. A sliding block itt is connected with the bottom portion of the bearing cup l (iii by dove tail means iSd. An upright adjusting rod itt has an inclined upper end portion itil which is connected by a pivot IEB with the sliding block ltd. The direction of movement of sliding block |54 in bearing cup itil is substantially at right angles to the axis of bearing studs i6! and the pivot Uitl is positioned to one side of the vertical axis of adjusting rod it@ so that longitudinal moveu ment of adjusting rod tt will tilt the bearing cup it@ and the sliding block its will pro-vide an adjustable connection between the adjusting rod i555 and bearing cup itil?.

The adjusting rod itt is positioned within a tubular upright shaft its which corresponds to either of the shafts or 'l of Figs. l to 17 and said shaft its is adapted to be driven in the same manner by similar worm drive means indicated generally by lili. The lower end portion of adjusting rod lei-5 has a transverse pin ill tightly tted therein and projecting outwardly through longitudinally extending slots il? in tubular shaft lei?. The outer ends of the pin ll'l are seated in a pin collar llt which extends around the tubular shaft its. The pin collar i253 has two flat race thrust bearings i-'ii positioned above and below it respectively. A bearing housing E encloses the collar il' and thrust bearings lid, said housing having an integral bottom portion iid and having a top cover ill secured thereto by screws i'iii so that bearings l'il are properly housed and supported, rI'he pin collar H3 and the bearing race members adjacent thereto rotate with the tubular shaft itil while the bearing housing lle and outer race members of the bearings are held against rotation. A frame bracket I'il secured to a xed frame member Idil by screws lil! extends upwardly and over the top of the bearing housing $15. The bearing housing i is supported for vertical movement on an upright post i232 and an upright adjusting screw H33. The lower end portion of the post E82 is threaded into a boss |311 which is rigid with the bottom i of the housing and the upper end portion of said post is connected with the frame bracket Il@ by a screw itil. The adjusting screw it?, is threaded into the bearing housing liti and the upper end portion of said adjusting screw is journaled in the frame bracket llt.

The lower end portion of the adjusting screw E33 is journaled in a bearing H86 secured to the bottom i of the housing. Washers lill are interposed between shoulders on the respective end portions of the adjusting screw i 83 and the bearing i3d and frame bracket il@ to serve as thrust bearings.

A horizontal shaft iiii is journaled in frame parts lim and i'iil and in another frame part |89. A turn knob illl is secured on the shaft it at the front side of the machine. A bevel gear ist is secured to the inner end portion of the adjusting shaft 188 and meshes with another bevel gear 52 which is secured to the adjusting screw A collar is?, on adjusting shaft prevents endwise movement in one direction of said shaft. Endwise movement of said shaft in the other direction is prevented by the hub of bevel gear ist and by a small sheave i951 which is secured to shaft E88 adjacent frame part i3d. Obviously turning of shaft ISS will rotate adjusting screw i313 and vertically move bearing housing lill. This will vertically move adjusting rod it and vary the inclination of bearing cup i553 and parts connected therewith.

A tilt angle indicator dial it, having a cylindrical peripheral portion provided with graduations, not shown, is mounted for oscillation on a bearing member 69S which is secured to a fixed bracket 197. An observation opening is@ shown by dotted lines in Fig. 18, is provided in the housing part 3. A sheave 99 is secured to the dial 495 and an endless flexible connector 2, preferably a wire, passes around this sheave |89 and the sheave iii. When adjusting shaft 188 is turned the sheave 156i will be turned therewith and the connector 26% will turn the dial |95 to properly register the inclination of the bearing cup i60 and parts connected therewith. Adjustment of the angle of the bearing cup ll may be made while the machine is in operation as well as while the machine is at rest.

The `bearing cup it@ carries a ball bearing 2id which receives a stub shaft 2&2 of an inverted cup member 203. Devices similar to those disclosed in Figs. 1 to 16 and correspondingly nurnbered are provided for imparting a toe-in and toe-out movement to the members gt3. An adjustable plate 284, corresponding to plate of Figs. 4, and 12, is mounted in dove tail means 255 in inverted cup member 263 and is movable in a direction parallel with the footplate by adjusting screw 2GB. Another plate member 'fill' is mounted in dove tail means 2&8 on the plate member 204 and is movable by an adjusting screw 299 in a direction crosswise of the foot- ,u

plate. An offset block Elli is held in position on the plate member 2'81 by dowel pins 2li and is secured to said plate member 261 by a screw 2 i2. A forward section 2i3 of a dual footplate is secured to the offset block 2m by screws 2M. Slots 215, only one of which is shown, are provided in the sides of the foot plate section 223 for the reception of straps 216 which may be fastened across the top of the foot of the person using the machine. A rear section 2! 'l of the dual footplate cooperates with the forward footplate section 213 to complete the footplate. The rear footplate section 2li has a shaft 2i8 rigidly fitted therein and secured thereto by a screw ZES. This shaft 218 extends downwardly from' the rear footplate section 2H and at right angles thereto and is pivotally seated in a suitable recess in a supporting column 22o which is secured to the top plate 5 of the housing. The shaft 2 lil may be quickly and easily lifted out of the recess in the column 22] when the dual footplate is to be removed and a one piece footplate, such as the footplate G shown in Figs. 1, 3 and 4 used; When the shaft 2 I8 is removed from the column 22S a cap, not shown, will preferably be placed on the top of this column. Os calcis support means, of a. form more fully shown in Fig. 15, is provided in the rear footplate section 2li and indicated generally by 22d.

The adjacent ends of the forward and rear footplate sections 23 and 2H are spaced apart as indicated by 222 to allow for relative angular movement therebetween. It will be noted that this break L22 in the dual footplate is substantially in alignment with the axis of the tubular shaft HES. A lining 223 of relatively thick and elastic sponge rubber is provided within the footplate sections 223 and 2H. The forward footplate section 213 has a universal tilting movement while the rear section thereof moves angularly from side to side. Thus a swash plate movement is imparted to the arch and toe portion of the foot while the heel portion is supported so that it will move from side to side. This imparts a very desirable corrective movement to the medio-tarsal joints of the foot. It has been found that many persons suffer from medio-tarsal joint trouble or trouble with the joints in the medial or arch portion of the foot just in front of the ankle. This may result from the wearing of shoes with high heels which have thrown the bones out of proper alignment at this location. 1t is desirable to correct this defect in order that full benefit may be derived from the use of the single footplates of the form shown in Figs. 1, 3 and 4. When treatments using the dual footplate shown in Fig. 18 are given the amplitude of the swash plate movement imparted to the footplate will be small, as the medio-tarsal portions of a normal foot admit of only a limited amount of movement.

It will be understood that the dual footplate shown in Fig. 18 may be applied to the machine shown in Figs. 1 to 17 and that the single footplate of Figs. 1, 3 and 4 may be applied to the machine shown in Fig. 18.

The provision for adjusting the inclination of the footplate while the machine is in operation is very desirable in a foot corrective machine because the correct amount of incline for some patients can best be determined by adjustment of the fcotplates while the corrective treatment is being given.
